My old age must be setting in, because I should know this...A few years back P.C. enhanced the design of the EAD to make the bottom ring thicker and stronger, and I believe they made a new barrel with more threads to go with it. Is this correct? If so, can the new barrel and ring fit onto the old style decorator "top"? Or does my customer have to buy a new EAD? She definitely has the "old" style ring and it snapped in half.
